Consider 3 of my last 10 mechanics I was using in the last 25 years went out of business in the bay area and people just don't repair old cars like the old days, I'd say it is a bad idea moving to SV as a mechanic, even if you are charging 150-200 / hr labor you may not be guaranteed a good income.Jeff, do you honestly think that AutoMech could load up his 1990 Mazda pickup with his tools, move to Silicon Valley and make a go of it? Where could he afford to live for starters? He'd have a tough time coming to small town Arizona and finding a place to live that wasn't a total dump on a new mechanic's wage. Things are different down in the trenches.
My new grad coworker's dad, doing repair on the side after his main job as a mechanic in a European shop, charging about $100/hr (because it is on the side), is classified as "low income" and qualified for partial section 8 subsidies. He is the single earner of a family of 4 (1 dependent child not yet working full time so for benefit it is a family of 3).
